Preliminary studies on tritium sorption in stainless steel under high pressure gas mixture of deuterium and tritium
The adsorption and desorption behaviors of tritium on the surfaces of stainless steel were studied prelimi- narily. After the exposure in the mixed gas of 50% deuterium and 50% tritium (15 MPa mixed gas
8 hours and 27MPa mixed gas
6 hours exposure at 503 K)
the tritium desorbed at room temperature and during heating up to 1173 K and the total sorbed tritium of the samples were measured. The results showed that the total adsorbed tritium was 857.4 MBq·cm-2
the desorbed tritium was 722.2 MBq·cm-2
the standard deviation of measurement was 6.49%. The tritium released from stainless steel at room temperature and during heating was mostly in the form of HT
The ratio of the free tritium to the total absorbed tritium was 7.34%. There were three peaks in the thermo-desorption spectrums of stainless steel
their desorption temperatures of the three peaks were 439
